Note de lecture : Capacités comme critères d’évaluation de système d’information

Ces Notes de lectures citent et commentent le texte dans sa langue originelle, ici l’anglais.

I am used to consider criteria such as human rights, exercises of power, effects on one or many lives, as well as informatics and society implications for doing social assessment of interpersonal information systems.

After hearing a lecture from Martha Nussbaum, I consider that it would be useful to also include consideration of capabilities. That would not provide brand new criteria, but certainly an additional angle to look at them.

« The capabilities approach » is « an outcome-oriented view that seeks to determine what basic principles, and adequate measure thereof, would fulfill a life of human dignity. » (Wikipedia, « Martha Nussbaum« , August 5, 2014)

Nussbaum identifies 10 core capabilities that, in her eyes, should be supported by all democracies:

  1. Life. Being able to live to the end of a human life of normal length; not dying prematurely, or before one’s life is so reduced as to be not worth living.
  2. Bodily Health. Being able to have good health, including reproductive health; to be adequately nourished; to have adequate shelter.
  3. Bodily Integrity. Being able to move freely from place to place; to be secure against violent assault, including sexual assault and domestic violence; having opportunities for sexual satisfaction and for choice in matters of reproduction.
  4. Senses, Imagination, and Thought. Being able to use the senses, to imagine, think, and reason—and to do these things in a « truly human » way, a way informed and cultivated by an adequate education, including, but by no means limited to, literacy and basic mathematical and scientific training. Being able to use imagination and thought in connection with experiencing and producing works and events of one’s own choice, religious, literary, musical, and so forth. Being able to use one’s mind in ways protected by guarantees of freedom of expression with respect to both political and artistic speech, and freedom of religious exercise. Being able to have pleasurable experiences and to avoid non-beneficial pain.
  5. Emotions. Being able to have attachments to things and people outside ourselves; to love those who love and care for us, to grieve at their absence; in general, to love, to grieve, to experience longing, gratitude, and justified anger. Not having one’s emotional development blighted by fear and anxiety. (Supporting this capability means supporting forms of human association that can be shown to be crucial in their development.)
  6. Practical Reason. Being able to form a conception of the good and to engage in critical reflection about the planning of one’s life. (This entails protection for the liberty of conscience and religious observance.)
  7. Affiliation.
    1. Being able to live with and toward others, to recognize and show concern for other humans, to engage in various forms of social interaction; to be able to imagine the situation of another. (Protecting this capability means protecting institutions that constitute and nourish such forms of affiliation, and also protecting the freedom of assembly and political speech.)
    2. Having the social bases of self-respect and non-humiliation; being able to be treated as a dignified being whose worth is equal to that of others. This entails provisions of non-discrimination on the basis of race, sex, sexual orientation, ethnicity, caste, religion, national origin and species.
  8. Other Species. Being able to live with concern for and in relation to animals, plants, and the world of nature.
  9. Play. Being able to laugh, to play, to enjoy recreational activities.
  10. Control over one’s Environment.
    1. Political. Being able to participate effectively in political choices that govern one’s life; having the right of political participation, protections of free speech and association.
    2. Material. Being able to hold property (both land and movable goods), and having property rights on an equal basis with others; having the right to seek employment on an equal basis with others; having the freedom from unwarranted search and seizure. In work, being able to work as a human, exercising practical reason and entering into meaningful relationships of mutual recognition with other workers. »

(Wikipedia, « Capability approach« , August 5, 2014)

This list of core capabilities is non exhaustive. Indeed, it can be enlarged.

For instance, outside welfare economics, one can add other capabilities that are pertinent to interpersonal information system, such as « privacy » as defined by Rohan Samarajiva as « the capability to implicitly or explicitly negotiate boundary conditions of social relations. This definition includes control of outflow of information that may be of strategic or aesthetic value to the person and control of inflow of information, including initiation of contact. » (Rohan Samarajiva, »Privacy in Electronic Public Space: Emerging Issues », Canadian Journal of Communication, North America, 19, Jan. 1994. Available at: <>).

A capability standpoint also reveals that such information inflow and outflow are far from exhausting this basic definition. Some « interflow » should also be considered: how, for example, intermediaries such as the Facebooks or Googles screen how one can be in contact with other or not, and how they could engage or not once contact is made.

As well, a capability standpoint can include an informational variation on the Practical Reason core capabilities. That is the capabilities to get, produce, process information to serve one’s own personal or collective goal.

Notes de lecture : Cavoukian, Ann. A Primer on Metadata: Separating Fact from Fiction

À propos de : Cavoukian, Ann. A Primer on Metadata: Separating Fact from Fiction (Information and Privacy Commissioner of Ontario, Canada, 1973).

Couverture de: Cavoukian, Ann. A Primer on Metadata: Separating Fact from Fiction (Information and Privacy Commissioner of Ontario, Canada, 1973)

Ces Notes de lectures citent et commentent le texte dans sa langue originelle, ici l’anglais.

Tweets from Privacy by Design (@embedprivacy) signaled the publication of A Primer on Metadata: Separating Fact from Fiction (18 pages PDF document). As I am currently working on a related subject, I read it at once… and was disappointed. The actual primer on what is metadata is only two pages long, rather minimal, inaccurate and not quite convincing.

Metadata (formal definition):

« Metadata is (…) essentially information about other information, in this case, relating to our communications. »

In this case : « Metadata is information generated by our communications devices and our communications service providers, as we use technologies like landline telephones, mobile phones, desktop computers, laptops, tablets or other computing devices. »

Cavoukian, 2013, p. 3

Metadata (descriptive definition) : « Metadata includes information that reveals the time and duration of a communication, the particular devices, addresses, or numbers contacted, which kinds of communications services we use, and at what geolocations. And since virtually every device we use has a unique identifying number, our communications and Internet activities may be linked and traced with relative ease – ultimately back to the individuals involved. »

Cavoukian, 2013, p. 3


As presented in the document, these two definitions are at odds with one another: the formal one referring to information items about other information items; but not the descriptive definition which is rather referring to information about processes. But computer specialists do recognize many kinds of metadata, even though they might use different typologies.

The few lines entitled « A Day in the Life… » (pp. 3-4) provide a good illustration of how (processes) « metadata created by the devices that two individuals use to communicate with each other can reveal a great deal » about them.

Finally, the section « Metadata May Be More Revealing Than Content » (pp. 4-5) reads more like a series of arguments from authority than as an actual demonstration.

Need for evidenced arguments

Coincidently, answering engineering students in a lecture made at Polytechnique Montréal last week, I had to remind that an information set would be metadata, not by some intrinsic nature, but merely by the context of its initial production and use. Classically, the term data referred to information items that are available (or to be produced) for the solution of a problem or the completion of a reasoning, an inquiry or a research. As soon as one so uses « metadata » (what ever the type), they become « data ». Thus, no longer are « metadata ».

From the very first universal purpose computing machine, computers – and digital devices since – require metadata to work. And they also produce other metadata as by-products of their processes. And from the dawn of informatics, those metadata were at once reused as data.

There is nothing new with using metadata to produce knowledge about people. A classic example is the introduction of the computerized cash registers. As the machine processes the customers’ purchases, it produces clock metadata than can be used to asses the clerks’ speeds to punch (now scan) items, to take payments and give change, to pack the goods and pass to the next customers.

Anytime an operation is linkable to a human user, the operations’ metadata can be exploited as data about this human user (and anyone related to that person). Videogames provides good examples of how the same outputs can simultaneously be processes’ metadata and players’ data.

These relative artificiality and mutability of the distinction between data and metadata become obvious when one considers (as these tweet structure maps show) that making a tweet of a maximum of 140 characters can easily require the production of between 500 and 1000 characters of metadata which include… the tweet message itself !

And indeed, the « metadata »/ »data » relative weights in todays’ particular instances can often be startling… if one can still distinguish between the two.

Also, need to make evidences evident

How come that there is no readily available button on which I could click to see the whole tweet actually produced, not only the message I wrote and sent?

Or how come that there is no readily available command to display what information my mobile phone service actually produces minute by minute?

And as I pointed out to Polytechnique’s engineering students: if NSA’s work is essentially done with computerized devices, how come Congress does not have a dashboard that harness the metadata about what kinds of operations NSA actually does? If such metadata would have been available, could Director James Clapper, been able to lie so easily about NSA’s operations before Congress? And Congress only discovering it through documents leaked by a whistleblower? After all, would it not be only metadata about systems’ uses, not data from the individual intelligence operations themselves? ;-)

Such are questions of critical and practical political significance. Because they breed other questions about who decides the production of such information. About its uses. About who control them. About their consequences. And so on. Of critical and practical significance also because they could turn a defensive stance into one of political affirmation. Such questions stem from an understanding of the nature of what information and information processing are. This is why it is so important to deepen and strengthen such understanding as well as to popularize it and make it useable by all citizens.

So if you know any instructive work on the subject…

Quelques notes tirées du livre de Luciano Floridi, The philosophy of information

Tiré de : Floridi, Luciano. The philosophy of information (Oxford [England]; New York: Oxford University Press, 2011).

Ces Notes de lectures citent et commentent le texte dans sa langue originelle, ici l’anglais.


Good problem / Open problem / Reseach Method

« Good problems are the driving force of any intellectual pursuit. Being able to do valuable research hugely depends on having good taste in choosing them. Now, for Hilbert, a good problem is a problem rich in consequences, clearly defined, easy to understand and difficult to solve, but still accessible. Again, it is worth learning the lesson, with a further qualification. We saw in chapter one that genuine philosophical problems should also be intrinsically open, that is, they should allow for genuine, reasonable, informed differences of opinion. Open problems call for explicit solutions, (p. 29 ) which facilitate a critical approach and hence empower the interlocutor. »

Floridi (2011) p. 28-29


Good problem / Reseach Method

« Hilbert thought that mathematical research has a historical nature and that mathematical problems often have their initial roots in historical circumstances, in the ‘ever-recurring interplay between thought and experience’. Philosophical problems are no exception. Like mathematical problems, they are not contingent but timely. »

Floridi (2011) p. 28


Solution / Explicitness / Rigor / Research Method

The more explicit and rigorous a solution is, the more easily it is criticizable. Logic is only apparently brusque. Its advice is as blunt as that of a good friend. The real trap is the false friendliness of sloppy thinking and obscure oracles. Their alluring rhetoric undermines the very possibility of disagreement, lulling the readers’ reason to sleep.

Floridi (2011) p. 28


Information / Epistemology

« The informational circle: How can information be assessed? If information cannot be transcended but can only be checked against further information—if it is information all the way up and all the way down—what does this tell us about our knowledge of the world?

The informational circle is reminiscent of the hermeneutical circle. It underpins the modern debate on the foundation of epistemology and the acceptability of some form of realism in the philosophy of science, according to which our information about the world captures something of the way the world is (Floridi (1996)). »

Floridi (2011) p. 40


Information / Epistemology / Model / Information Modelling / Reseach Method

« The semantic view of science: Is science reducible to information modelling?

The semantic approach to scientific theories (…), argues that

scientific reasoning is to a large extent model-based reasoning. It is models almost all the way up and models almost all the way down. (Giere (1999), p. 56).

Theories do not make contact with phenomena directly, but rather higher models are brought into contact with other, lower models (see chapter nine). These are themselves theoretical conceptualizations of empirical systems, which constitute an object being modelled as an object of scientific research. Giere (1988) takes most scientific models of interest to be non-linguistic abstract objects. Models, however, are the medium, not the message. Is information the (possibly non-linguistic) content of these models? How are informational models (semantically, cognitively, and instrumentally) related to the conceptualizations that constitute their empirical references? »

Floridi (2011) p. 41


Data / Information / Materialism

« Wiener’s problem: What is the ontological status of information?

Most people agree that there is no information without (data) representation. This principle is often interpreted materialistically, as advocating the impossibility of physically disembodied information, through the equation ‘representation = physical implementation’. (…) Here, let me stress that the problem is whether the informational might be an independent ontological category, different from the physical/material and the mental, assuming one could draw this Cartesian distinction. Wiener, for example, thought that

Information is information, not matter or energy. No materialism which does not admit this can survive at the present day. (Wiener (1948), p. 132)

If the informational is not an independent ontological category, to which category is it reducible? If it is an independent ontological category, how is it related to the physical/material and to the mental? »

Projet « Par delà la vie privée »CommunicationsNotes de laboVivre entre les lignesNotesNotes de lecture

Structure du message Twitter pour les nuls (2012)

Couverture provisoire du livre : Titre : « Vivre entre les lignes : la société de l'information à travers nos information personnelles » - Mentions : « Par delà la vie privée - Livre en chantier ouvert »

Ce billet porte sur le Projet « Par delà la vie privée » : VIVRE ENTRE LES LIGNES la société de l’information à travers nos informations personnelles.

Comme il s’agit d’un chantier de rédaction ouvert d’un livre de vulgarisation,

n’hésitez-pas à commenter !

Toute remarque aide à l’améliorer.

Plusieurs ont probablement aperçu la Map of a Twitter status object (structure objet d’un message Twitter) ci-dessous. Produit par Raffi Krikorian, du département d’ingénierie de Twitter, ce tableau d’une page est devenu vite populaire. Car, il illustrait en une seule image qu’un message Twitter ne résumait pas du tout à une simple ligne de texte de 140 caractères.

Même si ce document et ses annotations s’adressaient d’abord aux développeurs d’applications numériques, ils avaient une forte valeur éducative. Je l’ai utilisé souvent. Il fallait voir s’écarquiller de surprise et de curiosité les yeux des étudiants en droit de l’information! Il devenait aisé de passer le message qu’il faut faire ses devoirs lorsqu’on évalue une pratique informationnelle. Ne pas se contenter des seules informations et processus apparents. Il faut comprendre ce qui se passe réellement dans la boite noire. Quitte à demander un coup de main à des informaticiens.

Je rédige un nouveau chapitre de livre intitulé « Unités de production ». Il explique que le maniement d’objets informations nous permet d’en produire de nouveaux. Or cette tâche exige, souvent à notre insu, la production d’autres informations encore, soit pour la réaliser, soit pour la décrire. L’exemple du tweet de 140 caractères qui, en fait, comporte des milliers de caractères de lignes de code me semble excellent pour illustrer ce propos.

J’ai donc entrepris de produire un nouveau tableau qui serait à jour ainsi que plus clair, lisible et compréhensible par des non-spécialistes.

Liste partielle des informations liées à un tweet (petit)

Le résultat est ce tableau s’étalant sur deux pages. Cependant, il en aurait fallu trois pour être exhaustif. Cliquez ci-après pour accéder à :

L’exercice m’a, entre autres, révélé la présence de champs concernant le blocage de messages ou de comptes entiers d’utilisateurs à la demande d’autorités publiques, de détenteurs de droits d’auteur ou d’autres. Il m’a aussi révélé que la mappe n’est pas que celle d’un message (tweet), mais aussi de toutes les informations coproduites avec celui-ci. Dans la mesure, où toutes ces informations sont accessibles en pratique, la distinction ne relève peut-être que de la nuance. D’un point de vue pédagogique cependant, elle mérite d’être signalée.

Autre révélation, j’ai détecté dans le tableau originel de Krikorian quelques coquilles de syntaxe, de description et de statut des champs décrits. Étant loin d’être ingénieur chez Twitter, je vous serais fort reconnaissant si vous me signaliez toute coquille ou erreur dans le nouveau tableau ici proposé.

Worth reading: Adam Thierer's review of 'Consent of the Networked: The Worldwide Struggle for Internet Freedom'

Not only because of the growing power struggles over networks and contents, but also because of the crucial political debate about which strategies to maintain and expand freedom and democracy.

Thierer does nail some good critics, such as his section arguing that to treat Google and Facebook as "sovereign" (kind of Googledom, Facebookistan) is a self-fulfilling prophecy. But sometimes his critics of MacKinnon may read as weak as his presentation of her own case. His definition of "sovereign" reads a bit too classical XIXth century for contemporary realities. I also find his quest for a Net free from State intervention as naive as the quest for enlighten State regulation. The very protection of 47 U.S.C. § 230 he applauds because it shields online operators from liability for information posted or published on their systems by users actually is a State intervention that, not only has permitted the Yelp, Twitter, eBay to flourish, but also permitted them to become sort of public services.

Thierer recommends reading this book: I will certainly follow it. And I definitely recommend reading his take on it. I will certainly re-read it, and study both.

Rebecca MacKinnon’s new book, Consent of the Networked: The Worldwide Struggle for Internet Freedom, is well-researched exploration of the forces driving Internet developments and policy across the gl…

Des groupes formels et informels de Michel Cartier à groupes personnels et impersonnels pour PIP

En lisant Les groupes d’intérêts et les collectivités locales* de Michel Cartier, je tombe sur le schéma intitulé « Une société fonctionnant par paliers » qui distingue entre :

  • individu et couple (cercle représentant une tête humaine);
  • groupes informels (cercle rempli de sept têtes humaines);
  • groupes formels (cercle rempli de trois groupes de quatre à six têtes humaines interreliés entre eux); et
  • société (cercle représentant un globe terrestre).

Michel Cartier 2002

Groupe formel : « Regroupement de personnes qui revendiquent une meilleure qualité de vie et qui fonctionne à partir de l’inscription et de la participation de ses membres. »

Groupe informel : « Petit groupe familier fonctionnant en face à face »

Michel Cartier, 2002, p. 100

J’ai été particulièrement frappé par la distinction faite entre groupe formel et groupe informel. Ce qui m’a amené m’interrogé à savoir s’il y avait une différence conceptuelle à faire dans le modèle Portrait des Processus d’Information InterPersonnel (PIP) entre groupe ou population formels et informels.
